These apartments are huge and with small balconies - nice views.
Edward and the onsite staff are responsive and helpful - if you need extras in the apartment [wine glasses/tea towels] you can ask and housekeeping deliver.
We were there over a bank holiday weekend so the building was mostly empty and the shops below closed - the apartments are close to the Skytrain and shops and restaurants in Silom are within easy walking distance. Taxis and tuktuks available on the street outside for longer journeys
There is a convenient villa market grocery store nearby for supplies.
Our friends were first time visitors to bangkok so this was a good choice of location
